316L Stainless Steel Pipe

Description316L Stainless Steel Pipe Brief Introdcution316L stainless steel pipe is a hollow long round steel, mainly is widely used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts, etc.In addition, in bending and torsion strength, the weight is lighter, therefore it is also widely used to make mechanical parts and engineering structures. Futher It is also used to produce all kinds of conventional weapons, guns and shells.What is Stainless Steel 316L Pipe?‌316L Stainless Steel Pipe‌ is austenitic stainless steel pipe with low carbon (C≤0.03%)‌ and molybdenum (Mo:2–3%)‌, offering exceptional chloride corrosion resistance‌. Complies with ASTM A312/ASME standards‌, widely used in marine, chemical, and medical industriesSS316L TP316L AISI316L  316L Stainless Steel Pipe mainly contains chemicals of 16.00% – 18.00% Cr, 10.00% – 14.00% Ni, 2.00% – 3.00% Mo, ≤0.030% C， which is also a derivative steel of 18-8 type austenitic stainless steel with Excellent corrosion resistance.The American standard stipulates that the Ni content of 316L is 10-14%, and the Japanese standard stipulates that the Ni content of 316L is 12-15%.According to the minimum standard, there is a 2% difference in Ni content between the American standard and the Japanese standard, which is still quite huge in terms of price. Therefore, customers still need to see clearly when purchasing 316L products, whether the product is based on ASTM/JIS/DIN /EN/GOST standards. The Mo content of 316L Stainless Steel Pipe makes the steel have excellent resistance to pitting corrosion and can be safely used in environments containing halogen ions such as Cl-.Because 316L is mainly used for its chemical properties, therefore steel mills have slightly lower requirements for surface inspection of 316L (relative to 304). Customers with higher requirements on the surface should strengthen the surface inspection.‌Chemical Composition of 316L Stainless Steel Pipe‌ElementContent Range (%)Carbon (C)≤0.030 ‌Silicon (Si)≤1.00 ‌Manganese (Mn)≤2.00 ‌Phosphorus (P)≤0.045 ‌Sulfur (S)≤0.030 ‌Chromium (Cr)16.0–18.0 ‌Nickel (Ni)10.0–14.0 ‌Molybdenum (Mo)2.0–3.0 ‌Nitrogen (N)≤0.10 ‌Stainless Steel 316L Pipe PMI Test PictureSS316L/TP316L/AISI316L/1.4404/316L Stainless Steel Pipe PMI Test For Clients’ Reference,KCM SPECIAL STEEL Is Trustble Stainless Steel 316L Pipe Manufacturer And SupplierStainless Steel 316L Pipe Physical and Mechanical Properties‌PropertyValue Range‌Density‌~8.0 g/cm³ ‌‌Yield Strength (YS)‌≥205 MPa ‌‌Tensile Strength (TS)‌≥520 MPa ‌‌Elongation (EL)‌≥40% ‌‌Hardness (HV)‌~200 ‌‌Key Features‌:Superior corrosion resistance in chloride-rich environments (e.g., marine, chemical industries) due to Mo and Ti additions .Enhanced high-temperature stability and creep resistance ‌SS316L/TP316L/AISI316L/1.4404/316L Stainless Steel Pipe ‌Creep Rupture Strength & Thermal Conductivity at Elevated Temperatures‌‌1.
